Just bought my Ruger 556 MPR last month new. Noticed play or wobble with upper and lower receiver. Anyone else have an issue with this?

Upper/lower 'play or wobble' is common with any/all AR type firearms. It's a factor of tolerances. Usually doesn't affect function or accuracy. If you don't like it, get a package of the little polymer wedgie things that tighten the fit.
